The type of carbon fixation stores carbon dioxide in acid form is CAM i.e. crassulacean acid metabolism.
<h3>What are CAM?</h3>
CAM stands for crassulacean acid metabolism in this process photosynsthesis is occured at day time but the exchange of gases takes place at night itself only.
In this carbon fixation process, carbon dioxide is stored in the form of organic acid malic acid and losses carbon dioxide at the night time and by doing this it helps in the storage of water.
